Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of insulated bolts, it is recommended to prioritize confirming key technical parameters such as voltage level and mechanical strength to ensure compatibility with power equipment or high insulation scenarios.
  • In strong electromagnetic interference environments such as substations and rail transit, the material stability and weather resistance of insulation bolts directly affect their long-term performance, and specifications need to be selected based on specific scenarios.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • Insulated bolts of different specifications are suitable for scenarios such as distribution cabinets and new energy equipment. When purchasing, it is necessary to specify details such as thread type and insulation layer thickness.
